*1 The input voltage must be less than the output voltage for the converter to track the maximum power point.
*2 Maximum under NTP conditions with natural convection.
*3 The input current and output voltage will be limited to a value required by the customer.
*4 Depending on application, peak efficiency is reached with a low boost factor. Higher boost factors will decrease efficiency.
